一、自动空气制动机的产生和发展 1869年,美国乔治·威斯汀豪斯发明了直通空气制动机。但由于当时美国铁路的列车广泛使用简单的链子钩和销接连接,因而,列车分离是经常发生的。为使列车中的所有车辆在意外分离时,都能自动制动,威斯汀豪斯于1872年又发明了自动空气制动机。自动空气制动机比直通空气制动机优越得多,安全得多。因为它能使列车在意外分离的情况下,保证所有车辆上的制动机都能自动制动,而且制动作用更快,更一致。虽然,最初的自动空气制动机还只能使货车的
First, the automatic air brake production and development In 1869, the United States George Westinghouse invented the through-air brake. However, because of the widespread use of simple chain hooks and pin-to-pin connections on U.S. railroads at the time, train separation was frequent. In order to make all the vehicles in the train accidentally separated, can automatically brake, Westin House in 1872 invented the automatic air brake. Automatic air brakes are much superior to straight air brakes and are much safer. Because it keeps the train apart accidentally, it ensures that all the brakes on the vehicle are automatically braked and the braking effect is faster and more consistent. Although, the original automatic air brake can only make the truck
